I can't sync new songs to icloud anymore.
2024/10/06 I open Apple Music Windows App,and version is 1.5.0.152 (1.1280.38913.0)
As usual, I added music that was not in Apple Music to the library locally. In the past few days, I could still see and play to it on other devices (iPhone 13, iPad Air 6) after synchronizing the library. But starting today, I can only see the cover, title, lyrics and other information of the song on my other devices, but the song title turns gray (with a cloud with an X symbol). When I want to play it, The system keeps asking me to synchronize the database on the PC, but I have synchronized several times and still cannot play the songs I added on devices other than the PC (only the PC can play). I've tried re-downloading the PC, iPhone, and iPad, and re-logged in to Apple Music on all devices, but the problem still hasn't been solved.
Windows, Windows 10 (19045)
